panic: Fix panic message visibility by calling bust_spinlocks(0) before dying
Commit ffd71da4e3f ("panic: decrease oops_in_progress only after
having done the panic") moved bust_spinlocks(0) to the end of the
function, which in practice is never reached.
As a result console_unblank() is not called, and on some systems
the user may not see the panic message.
Move it back up to before the unblanking.
